DEVICE FOR HOLDING VALVES- SPEGIFICATION forming part of Letters PatentNo. 793,419, dated June 27, 1905.

Application filed April 2, 1904- Serial No. 201,225.

To all whom it may concern:

Be it known that I, CHRIsToPHER O. COLE, a citizen of the United States,and a resident of Bellingham, in the county of VVhatcom and State ofWashington, have invented a new and Improved Device for Holding Valves,of which the following is a full, clear, and exact description.

My invention relates to a device for hold- IO ing valves and preventingtheir displacement when they are subjected to jarring or other motions.

The principal object of my invention is to i provide for holding valvesas stated and at 5 the same time permit them to be opened and closedwithout the necessity of loosening or tightening any of the parts orusing separate tools of any kind.

Further objects Will appear in the course of the subjoined description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

2 5 Figure 1 is a plan view of a valve-casing with a preferred form ofmy invention applied. Fig. 2 is a side view of the same, partly insection, on the line 2 2 of Fig. 1. Figs. 3, 4, and 5 are perspectiveviews of de- 3 tails; and Fig. 6 is a fragmentary sectional view on theline 6 6 of Fig. 1.

In the drawings, 7 represents a valve-casing havingaprojectingvalve-stein 8. I have shown a Lunkenheimer valve, and my device isespecially applicable to this type; but it is to be understood that myinvention is not limited thereto and that it may be applied to any kindof a valve.

9 is an ordinary lever used with certain 4 types of valves. Thevalve-stem is provided with a square portion 10, as is usually the case,for the reception of the lever 9; but it should preferably be madelonger when my improvement is to be used, and it is shown as suppliedwith a screw-thread 11 for the reception of a clamping-nut.

The main part of-the holder consist-s of a friction-plate 12, shown asformed of two pieces of sheet metal, one superposed upon the other; butit will be obvious that it may 5 be formed of a single piece or of morethan two pieces and that it may be formed of other materials than sheetmetal. At one end it is bent down, as shown at 13;for the purpose ofabutting against a stationary object in order to secure it in a fixedposition. It is also provided with a perforation 14, which should belarge enough to permit the valve-stem and other parts to pass throughwithout contacting'with the edges of the perforation. A pair of specialwashers 15 16 is provided to bear upon the opposite sides of thefrictionplate,

as shown. These washers are provided with holes 17 18, which arepreferably of the shape of the end of the valve-stem and fit close 5enough to it to be compelled to move with it. They are also providedwith flanges 19 20, those on the upper washer extending downwardlythrough the perforation 14 and those on the lower washer extendingupwardly 7 through the same perforation. These two flanges arepreferably formed on the same side of each washer and on opposite sidesof the hole through the Washer, tWo being used on each Washer. The twosets of flanges are preferably located at ninety degrees to each other,so that taken together they substantially surround the valve-stem.

The usual common washers and nut, as well as a jam-nut, may be employedto hold the special washers in position, and the construction is suchthat the two special washers will be forced into frictional contact withthe friction-plate 12, and thus will be held from rotation when anyordinary jarringor other motion 5 is communicated to the valve-stem orother parts of the valve. When it is desired, however, to turn the lever9, this can be done in the ordinary way by overcoming the frictionalresistance of these parts and Without the use 9 of'tools or theloosening of the nut. A convenient manner of holding the friction-platein position is illustrated in the drawings.

21 is a clamp having projecting pieces 22 and perforations 23. Throughthe perforations 23 passes a bolt 24, which is adapted to tighten theclamp in the ordinary way around any object upon which it may beplacedas,

for example, a pipe 25. In the use of this clamp the projection 13 onthe plate 12 will be placed against the pipe 25, and the clamp uponbeing tightened will hold the frictionplate securely to the pipe. Thisis an important part of my invention, but it will be obvious that thefriction-piece could be clamped to any other stationary object withoutdeparting from the spirit thereof.

It will be evident that by the use of this de vice the lever can beclamped in any position, so that the jar of the machinery to which thevalve is attached will not cause the same to be displaced, and at thesame time will permit the valve to be opened and closed in the ordinaryway. Of course, if desired, it can be clamped tight enough to preventmovement of the lever and valve without loosening the nut by means of awrench.

It is to be understood that my invention is capable of embodiment inmany other forms than that illustrated and that many modifications canbe made in the same without departing from the spirit of the invention.

Having thus described my invention, I claim as new and desire to secureby'Letters Patent-- l. A valve-holder, comprising a plate having aportion extending from it at an angle thereto, a clamp for engaging andholding said portion, and frictional means for securing a valve-stem tothe plate.

2. A valve-holder, comprising a plate having an arcuate portionextending from it at right angles thereto, a clamp for engaging andplate, and means for fixedly holding the washer with respect to thevalve-stem.

4. The combination with a fixed frictionplate, of washers in frictionalengagement therewith, said plate and washers having passages for avalve-stem, and means on said Washers for securing them with respect tothe valve-stem.

5. A device for holding valves, comprising a friction-plate having apassage therethrough for a valve-stem, a washer in frictional contactwith the plate and having a perforation registering With said passage, aflange projecting into the passage in the plate and means for securingthe valve-stem with respect to said plate.

6. A friction-plate for a valve-holder having a perforation, and acurved edge bent at right angles to the body of the plate.

7. The combination with a fixed frictionplate, of two washers infrictional engagement therewith, one on each side thereof, said plateand washers having passages therethrough for a valve-stem.

8. The combination with a fixed frictionplate, of a Washer on each sidethereof in frictional engagement therewith, said frictionplate havingapassage therethrough, and each of said Washers having a flange locatedin said passage.

9. A friction-plate for a valve-holder, having a perforation, and acurved serrated edge bent at right angles tothe body of the plate.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
